    2005 RXP to X Charger

    I am working on a jet ski for someone that had recently had a ceramic thrust washer failure. I was going to rebuild the supercharger but was looking at superchargers through the performance parts on here. I saw they offer an x charger with injectors for a reasonable price. Reasonable enough to consider this route and hold off on rebuilding the old super charger. I looked at the x compressor wheel and housing to add to the old supercharger but it did not seem as cost effective as a new x supercharger. To do the x supercharger are the 42lb injector really all that is needed or will an ecu reflash be required or a different ecu be required.

    Your stock ecu will work fine. Need the 42's.

    Thank and another question. Are there any options for a different impeller to swap that would fit the original housing and be comparable to the x supercharger in performance?

    Yep, ET127. Awesome little wheel!!!! Alot of people that have ran both the x and the ET say the ET is better.

    remember with the 215 sc the biggest wheel is the 127
    x charger can hold a 137 and the water cooler

    A X-Charger wheel will NOT fit in your housing..you either need to get a complete X-Charger or go with the ET 127 wheel...Which IMO is not a bad route to go if you have an existing 215 Scer and are not ready to go with a complete charger....BUT seeing your finances are good and your pointng on buying the Charger/injector combo,then i would go that route as then you can upgrade wheels in the future if you want and not have to worry about buying another housing...

    X charger likely makes the most sense if the stock charger requires a rebuild. That being said I run the ET 127 and love it. Remember you will likely need to re pitch the prop with either of these set ups.
